Orlando Bloom gets his flirt on with rising starlet Margot Robbie

Judging by Orlando Bloom's dating history, he has a soft spot for statuesque Aussies (estranged wife Miranda Kerr) and willowy blondes (ex-girlfriend Kate Bosworth). But has he found an irresistible combination in awards-season darling Margot Robbie?

Page Six says the actor-turned-world's most adorable dad, 37, seemed to show "a lot of interest" in the "Wolf of Wall Street" beauty, 23, during a CAA-sponsored Golden Globes afterparty on Sunday night.

"There was flirting going on at the party, and why not?" notes a source. "She is single and gorgeous."

Star magazine, meanwhile, takes their tête-à-tête a step further, alleging their instant chemistry led to a make-out session in a corner.

"Everybody was a bit surprised at how forward they were," contends a spy, "but they didn't seem to care."

But the Page Six insider downplays the alleged lip-locking. Later that night, both attended a Diddy-hosted party that turned into a star-packed, champagne- and tequila-fueled birthday celebration for Bloom.

Orlando amicably split with Kerr in October after three years of marriage and one cutie-pie son together.

Back in November, Robbie was forced to deny tabloid reports linking her to Will Smith, her co-star in the forthcoming "Focus," after the two playfully posed in a photo booth.

"There's absolutely no truth to the ridiculous rumor in Star mag," she tweeted. "It's disappointing that goofing around on set could be taken so out of context."

During her red carpet stroll at the Globes, Margot said she was single but not looking to mingle with her fellow thespians.
